Removed this bit:

• Shared Universe: Going by the stories, Death's Head has encountered the Transformers, the Seventh Doctor, and the mainstream Marvel universe (both present and future). Best to just chalk it up to the multiverse...

Note that part I bolded. The Multiverse, means that all those things are separate universes, while Shared Universe would mean they are not. Contradictory there. See Trope Repair Shop thread.

I'm disappointed this article doesn't start with "Describe Death's Head here, yes?"
